Abstract

L'invention concerne un transducteur acoustique dynamique doté d'une membrane (10) présentant au moins une première et une deuxième surface métallisée (11) séparées l'une de l'autre par une surface isolante (12). Le transducteur acoustique dynamique comporte également une bobine mobile (20) constituée d'un fil (25), dont une extrémité est reliée de manière électroconductrice à la première surface métallisée (11) et dont l'autre extrémité est reliée de manière électroconductrice à la deuxième surface métallisée (11).
